A double-ended queue (dequeue or deque) is an abstract data type that generalizes a queue, for which elements can be
added to or removed from either the front or rear. Deque differs from the queue abstract data type or First-In-First-Out List (FIFO),
where elements can only be added to one end and removed from the other. We have given more details on Deque in the previous
example

The only difference between StringBuffer and StringBuilder is StringBuffer
